Turn on the news or look at Twitter, and it's likely you'll be bombarded by outrage. Many people have come to believe that the only way to spark change is to incite anger. This week on Hidden Brain, how outrage is hijacking our conversations, our communities, and our minds.

Babies are speaking to us all the time, but most of us have no clue what they're saying. To researchers, though, the babbling of babies is knowable, predictable, and best of all, teachable to us non-experts. This week, we revisit our May 2018 primer on how to decipher the secret language of babies and young children.

More than 70,000 people died of drug overdoses in 2017 — many of them from heroin and other opioids. One of the most widely-used tools to confront this crisis is a drug called naloxone. It can reverse an opioid overdose within seconds, and has been hailed by first responders and public health researchers. But in 2018, two economists released a study that suggested naloxone might be leading some users to engage in riskier behavior — and causing more deaths than it saves. This week, we talk with researchers, drug users, and families about the mental calculus of opioid use, and why there's still so much we're struggling to understand about addiction. This episode originally aired in October 2018.

As a society, we talk about sex more openly today than ever before. But so much still goes unsaid. This week on the Hidden Brain radio show, complicated stories of intimacy and attraction.

Generations of Americans have struggled against segregation. Most of us believe in the ideal of a colorblind society. But what happens when that ideal come up against research that finds colorblindness sometimes leads to worseoutcomes?

Many of us intuitively feel that the bitter partisanship of American politics is bad for our nation. So should we be concerned about the health of our democracy? This week on Hidden Brain,we revisit two of our favorite conversations about U.S. politics. We start by talking with political scientist John Hibbing about the psychological differences between liberals and conservatives. Then, we explore the role of conflict in democracy with historian David Moss.

If you've taken part in a religious service, have you ever stopped to think about how it all came to be? How did people become believers? Where did the rituals come from? And what purpose does it all serve? This week, we bring you a July 2018 episode with social psychologist Azim Shariff. He argues that we should consider religion from a Darwinian perspective, as an innovation that helped human societies to thrive and flourish.

How many ads have you encountered today? On this week's radio show, we discuss the insidiousness of advertising in American media.

If you've ever flown in economy class on a plane, you probably had to walk through the first class cabin to get to your seat. Maybe you noticed the extra leg room. The freshly-poured champagne. Maybe you were annoyed, or envious. Social psychologist Keith Payne says we tend to compare ourselves with those who have more than us, but rarely with those who have less. This week, we explore the psychology of income inequality, and how perceptions of our own wealth shape our lives.

The desire to find our tribe is universal. We like to know who we are and where we belong. This fascination has led to a thriving industry built on the marketing and sale of personality tests. These tests offer individuals – and, increasingly, employers – quick and easy insights that can be used to make some of life's biggest decisions. But most fail to stand up to scientific scrutiny. This week, we revisit our 2017 episode about the world of personality testing, and explore the many different ways we assess personality and potential – from the Chinese zodiac to Harry Potter houses to the Myers-Briggs test.
